Once commercial operation begins, Powin will include a 50% stake in its 8.8 MW/40.8 MWh system in Stratford, Ontario that is under contract with Ontario IESO. The system is expected to go online by the end of 2017 and will be the largest battery storage facility in Canada. Details on a 10 MW/40 MWh project will be announced later.
